Dear All:
Version 1.1 of the TerraLook desktop software has just been released
and
is available at
http://terralook.sourceforge.net
This free desktop software is a
simple and intuitive image processing and GIS package.
TerraLook provides free, recent and historical satellite images in a
simple jpeg format. Although no special software is required to use
the TerraLook images, we do offer the TerraLook desktop software for
those who wish to manipulate images and overlays. More information
on TerraLook, including how to order images, is provided below, or just
go to
http://terralook.cr.usgs.gov
V1.1 is a big improvement over V1.0. Aside from internal
improvements and bug fixes it supports a variety of new capabilities
including true pan, image adjustment, collection merging, user-settable
preferences, and is fully multilingual in English and Spanish (menus
can
also be viewed in French but the Help has not yet been translated).
V2.0, which will completely remake the look and feel, will be available
in 2009.
Comments welcome!
Best wishes,
Gary
1. The US Geological Survey is the “operational partner” with NASA
and they provide the tools to find and order the images. They are
also working on outreach and providing materials explaining how images
can be used and for various workshops. The TerraLook website is
at
http://terralook.cr.usgs.gov
2. To obtain images the process is simple:
- Select and Order Images. Use the USGS “GloVis” tool, which is
explained at the above website.
- You will receive an email message and download instructions
when your
order is ready.
- Download a zip file which contains the images and other
information.
- Use the free TerraLook software, or any software tool of your
choice,
to view and work with the images.
3. Full-country image collections have been created for many
countries and can be downloaded--no need to order them. These are
available at
http://asterweb.jpl.nasa.gov/TerraLook_download.asp
Currently
available countries include:
- All of Central America
- All of South America
- All of Southeast Asia (except for some Indonesian islands)
- India
- Much of Africa
- Miscellaneous other countries
For most countries coverage includes: complete coverage for 1975,
1990, and 2000, and coverage of protected areas from 2000-2007
NOTE: Most of these collections are large and require a very good
Internet connection (apologies for that; size is specified in the .txt
file associate with each collection.) We hope that CD or DVD
distribution can be routinely available in the future; in the meantime
I
can send out a limited number by CD/DVD for those with no other
options.
4. The images are in a "georeferenced JPEG"
format. Being JPEGs, essentially everyone with a computer has an
appropriate tool to view them. And being georeferenced means that,
with any tool that has some GIS capabilities you can add overlays such
as
park boundaries, poaching sites, and trails.
5. The free TerraLook software is one of these GIS tools. It
is a free, Open Source package that supports common GIS and Image
Processing functions. One advantage of this software is that it
displays the "footprints" of all the images in a
collection--very useful for finding the specific image of interest in
collections with more than just a few images.
